Problem is, the company sells a no risk, 100-percent satisfaction guarantee for its treatments, which run between $8,000 to $12,000.

Charles Stevenson gave up trying to call and headed down to Bennis’s office, at which point the receptionist offered him six more months of treatment at a discounted rate. When Stevenson declined, Bennis stormed out of his office “enraged” and “approached Mr. Stevenson in an intimidating manner.”

Madigan’s suit seeks full restitution for customers who were duped, thousands of dollars in fines, and a ban on practicing their hair-brained schemes in Illinois.

A representative for Bennis told the Tribune that the president stands behind his business, and called the suit nonsense.
